Answer:
An earthquake is the sudden movement of the Earth's tectonic plates, resulting in shaking of the ground. This shaking can result in the damage of various structures such as buildings and further breakdown of the Earth's surface.
The study of earthquakes is called seismology.[1] There can be many earthquakes over a short time frame in a small area. The sudden release of tension in the tectonic plates sends waves of energy that travel through the Earth. Seismology studies the cause, frequency, type and size of earthquakes.
Earthquakes are measured using observations from seismographs. The magnitude of an earthquake and the intensity of shaking is usually reported on the Richter scale. The Richter Scale was invented by Charles Francis Richter in 1935. On the scale, 2 is scarcely noticeable, and magnitude 5 (or more) causes damage over a wide area.
An earthquake under the ocean can cause a tsunami, which can cause just as much destruction as the earthquake itself in mountainous areas. Earthquakes can also cause landslides. Earthquakes are part of the Earth's natural rock cycle. The impact of an earthquake can be measured by a seismometer. It detects the vibrations caused and it puts these movements on a seismograph. The strength, or magnitude, of an earthquake, is measured using the Richter scale. The Richter scale is numbered 0-9. The largest earthquake ever measured was a 9.5 on the scale a 10 has never been recorded.
Scientists cannot predict an earthquake before it happens. But we do know where earthquakes might happen in the future, like close to fault lines. An earthquake under the ocean can cause a tsunami, this can cause just as much destruction as the earthquake itself.
There are three main types of geological fault that may cause an earthquake: normal, reverse (thrust) and strike-slip. Normal faults occur mainly in areas where the crust is being extended. Reverse faults occur in areas where the crust is being shortened. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other.

Answer:
Earthquake : A earthquake is the shaking of the earth resulting from a sudden release of the earth 's lithosphere .
Volcano : A volcano is a repture in the crust of a planetary mass object, such as earth that allows hot lava, volcanic ash and gases to escape from a magma chambell the surface .
Floods : A flood is an over flow of water that submerges land that is usually dry.
Cyclone : A cyclone is a large scale air mass that rotates around a strong centre of low atmospheric pressure.
Drought : A drought is an event of prolonged shortages in the water supply wheather atmospheric surface water or ground water
